As reported by Dr. Mario Garcia, Director of Cardiac Imaging at Mount Sinai Hospital in New York, coronary artery disease, or CAD, kills about 500,000 Americans every year, and doctors now believe that half the world's population will develop CAD over the course of their lifetimes. CAD is one of the leading causes of death and disability in both the emerging and developed world. "The most common risk factors are diabetes, high blood pressure, abnormal cholesterol and cigarette smoking," says Garcia. "Next in line is obesity, which is important because it's closely related to diabetes and high blood pressure."
